"The purpose of this letter is to notify you that on the 21 July, after most careful consideration, the Home Secretary personally directed that you should be excluded from the United Kingdom on the grounds that your presence would not be conducive to the public good in the light of your character, conduct and associations. You have no right of appeal against this decision."
"So far as that is concerned the entry clearance officer in Nairobi was aware when permission to enter was granted in April 2005 that serious allegations of corruption had been made against the claimant. What changed between then and the decision in July was that the Secretary of State became aware that when the claimant was in the United Kingdom he had been involved in activities connected with these allegations."

If it is so withheld and yet the judge takes such information into account in reaching his conclusion without disclosure to those parties who are properly and naturally vitally concerned, were the proceedings cannot be described as judicial."
"... the fundamental principle of justice that the judge should not look at material that the parties before him have not seen."
"Based on Lord Bingham's approach it can therefore be accepted when determining the outcome of the issue that fairness is a 'constantly evolving concept'. Provision has to be made when it is necessary for derogation from the golden rule of full disclosure but the derogation must be the minimum necessary to protect the public interest."
"None of these problems should deter the court from appointing special counsel where the interests of justice are shown to require it. But the need must be shown. Such an appointment will always be exceptional, never automatic; a course of last and never first resort. It should not be ordered unless and until the trial judge is satisfied that no other course will adequately meet the overriding requirement of fairness to the defendant."
"What changed between then and the decision in July was that the Secretary of State became aware that when the claimant was in the UK he had been involved in activities connected with these allegations."
